During the last reporting period there was documentation of a tremendous response of bladderpod to active management efforts. In the first case, the Army Corps of Engineers has been actively managing a small limestone glade at Beaver Lake in NW AR. The glade was overgrown with cedars and other hardwoods that shaded out the glade. Following thinning operations, prescribed fire, and control of exotics, the population at this site increased from a handful of plants to several thousand. In the second case, the National Park Service at the Wilson Creek National Battlefield in Springfield, Missouri performed prescribed fires on an overgrown glade and the results were monumental as the bladderpod population at this site increased from 250 plants to tens of thousands following a prescribed fire in August 2011. These observations clearly demonstrate that this species can thrive with proper management.

A management plan for Missouri bladder-pod in Arkansas was completed Oct. 30, 2008 by Theo Witsell of the Arkansas Natural Heritage Commission. It was funded out of FWS "Showing Success" funds- Coop. Agree. # 30181-6-J204

In May of 2013, a new population of Missouri bladderpod was discovered in Greene County, Missouri. This is a county where approximately 50 sites exist. Most observers in Missouri and Arkansas reported that this was an excellent blooming year for the species but there was insufficient time to conduct population estimates at each site.
In May 2014, an interagency survey for the species was conducted in southern Missouri and northern Arkansas. Partners who participated in the survey were the FWS, Arkansas Natural Heritage Commission, the Missouri Botanical Garden, the Missouri Department of Conservation, the Army Corps of Engineers (COE), and the Botanical Training Institute. One new site was discovered in Washington Co., AR adjacent to an extant site at Beaver Lake. The new discovery will enable the COE to expand management activities between the new site and the adjacent locality. This will provide the opportunity to increase the size and extent of the population at Beaver Lake. Additional surveys in appropriate habitat is further warranted.

Includes post delisting monitoring following a final rule delisting the species.
Irregular monitoring continues throughout the species' range. Most monitoring simply involves presence/absence surveys or a rough estimate of plants, but detailed demographic monitoring has been conducted at 7 sites at the NPS' Wilson Creek National Battlefield. In 2013, during the last reporting period, results of monitoring at these sites between 1988 and 2013 resulted in the following publication: Annual Status Report- Missouri Bladderpod Monitoring for Wilson's Creek National Battlefield, 1988-2013 by Craig C. Young. Monitoring at these sites indicate that populations fluctuate up and down in relation to environmental and edaphic variables. Other sites monitored in AR and MO provide continued evidence that the species responds favorably to different types of disturbance, especially late summer prescribed fires conducted the summer prior to the next spring flowering period.

Management studies to study the efficacy of various herbicides in controlling exotic brome grasses (Bromus spp.) at selected Missouri sites and the potential impact of future development on sites in Missouri under private ownership will be initiated fall 2006/spring 2007 with FY 2006 "Species Showing Success" funds.
This report involved two phases: the first involved a land owner contact questionnaire regarding the willingness of private landowners to conserve Missouri bladderpod and to assess whether it was likely that their land was scheduled for development anytime in the foreseeable future. The second phase evaluated different methods to control invasive species of brome grass using various herbicides. Bowe noted that of the land owners who responded, the overwhelming majority were interested in conserving the species on their property and none indicated any future development on their property that could potentially impact bladderpod habitat. Results of the herbicide treatment study indicated that the best method for controlling brome grasses was to use multiple herbicides in tandem or synergistically. The author also suggested that herbicides should be used in rotation with fire due to the ability of some invasive species to be able to develop a resistance to various herbicides if applied in successive years.
